protobuf_source

A single Protobuf file used to generate various languages.

See Protobuf and gRPC.

dependencies

type: Iterable[str] | None
default: None

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib'].

Alternatively, you may include file names. Pants will find which target owns that file, and create a new target from that which only includes the file in its sources field. For files relative to the current BUILD file, prefix with ./; otherwise, put the full path, e.g. ['./sibling.txt', 'resources/demo.json'].

You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.

description

type: str | None
default: None

A human-readable description of the target.

Use ./pants list --documented :: to see all targets with descriptions.

grpc

type: bool
default: False

Whether to generate gRPC code or not.

python_interpreter_constraints

type: Iterable[str] | None
default: None

The Python interpreters this code is compatible with.

Each element should be written in pip-style format, e.g. CPython==2.7.* or CPython>=3.6,<4. You can leave off CPython as a shorthand, e.g. >=2.7 will be expanded to CPython>=2.7.

Specify more than one element to OR the constraints, e.g. ['PyPy==3.7.*', 'CPython==3.7.*'] means either PyPy 3.7 or CPython 3.7.

If the field is not set, it will default to the option [python].interpreter_constraints.

See Interpreter compatibility for how these interpreter constraints are merged with the constraints of dependencies.

python_source_root

type: str | None
default: None

The source root to generate Python sources under.

If unspecified, the source root the protobuf_sources is under will be used.

source

type: str
required

A single file that belongs to this target.

Path is relative to the BUILD file's directory, e.g. source='example.ext'.

tags

type: Iterable[str] | None
default: None

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run ./pants --tag='integration_test' test :: to only run on targets with that tag.
